Be it known -thatIfTHoMAs'GL-KU'S, a citizen of the UnitedStates'reSidingat Chicago, Cook County, 1llinois, have invented certain@new and useful Improvements in Coke-'Oven Doors and the like, of which'the following is a specification.

This invention relates to certain improvements in the construction ofdoors andthe like. 'The invention' has particular refer-l ence tothe'construction of doors for usevin connection withretort coke ovens,'and-for this reason, I haveV hereinV illustrated and willl particularlydescribe the features of the Vpresent invention as applied to such use.I wish it Y'distinctly understood, however, that-in so doing donot'inteiidthereby tojin any mannerV limit the application of theinvention to suoli use except as' I' may do so in the'claims.

.fletort v coke oven doc-rs` are relatively large" and iheavy, 4 and arergenerallyi of. considerably elongated` formln Itv -is' common practice,to line or'face the :inner surface of suclild'oors with-silicaA bricksof blocks, or

" other material of highly refractory nature.

ln order tofprevent damage tov such llinings'- by jamming' orstrikingagainst .stationary portions of the ovens', it 1s very desirableto provideV mee'ans onthe doors whereby they can be very securelygrippedand sustained' by the door handling mechanism. jOne` of the ob#jects of the invention 'isto provideV a construction of door andattachments therefor whereby the door handling apparatus :may

Atake such a definite andu firm hold ofthe door vas to effectuallyVprevent any undesirable and improper movements ofv they door withrespectto -the door handling apparatus.

Another `feature ofthe invention has toY dowith the construction of thelocking ldevices wliereby'the door is held securely in position withrespect. to the oven- In this connection, one of the objects of theinvention is to provide a very-simple Vand effective f locking devicewhich may be readily jat-V tachedv to'or detached from fthe ,door Aface'without change 4of the construction of the fdooritselfyand'a klockingdevice which in service will' effectuallyco-operate with suit- A ablestationary eleinentslocated for exam ple, upon thebuck-stays so as tollock the.I 'door in position@v y' Another feature of the invention hasto.

used as themea'nslor element with Whichthe of such a v'construction thatit may also be Aj?? door handling machine directly coi-operates intheop'eration of removing'the door'from theroven or seating it inposition. ln: this connection, another feature o f the'invention Y isrtoprovide a locking device of such form and arrangement .that in thenormal 'opera-'- tion of engaging it by theV door handling Amachine itWill be. automatically unlocked' from-the stationary elements With Whichit also so constructed that'in the operation of engaging it bythelifting or handling 'mechanism the locking' device is rst unlocked fromthestationary elements, so' that when the vtime comes for'v removing or`disengag- V ing the door from the stationaryl structure,

`this connection, ia' further object of the *i Y.

invention is to'soassociateorV combinel the; door handling mechanismwithl the' door sov andl its locking devices that in the reverse loperation of seating the door" and' disen-V gagi-ng `thekdoor Vhandlingelement there# from, Athe Vlocking device lwill be automati-y callylocked rmly in positionso vas to lock the door :before the doorlhandlingmachine invention f construction and combinations of parts here-i. fV

These buck-stays when used, constitute a convenient elementor structure to which may be secured suitable abutments for engagementby the locking devices on the door. lt will be understood, however, that,as far as the use of buck-stays and door jambs are concerned, thefeatures of the present invention might be used inmany otherassociations or combinations than that illustrated in the drawings.

In the construction illustrated there are provided two of the lockingdevices designated by the numerals 10 and 11 respectively. The use oftwo locking-devices is generally recognized practice, and when two ofthese devices are used, they insure a solid and even locking of the doorinto position. rlhey also serve t0 insure the application of a moreuniform lifting effort on the door, .and also when used," servetovprevent the door from tilting `with respect to the Ydoor machine. ltwill be understood, however, that in many A Y cases single` lockingdevice may be used,

and that i contemplate within the scope of my invention, the use of oneor more locking devices and do not limit myself to the use of two ofthem except as'I may do so in the claims.

Bearingtne foregoing in mind, each locking device comprises abraclet 12secured to the face ofthe door, and generally provided withtwooutstanding flanges 13 and .14. in

some Vcases a single flange will befound satisfactory. TWithin these'flanges there are provided slots V15, and extending-through the iangesof each locking device is a locking pin 1G which is free-to move up ordown within the slots of its locking device,as will be readily apparentfrom inspection of the seveial figures. Any suitable `means Vorconstruction may be provided for retaining the pin in place in itslocking device, as for example. a collar 17 located upon the pin lat apoint between the flanges, and secured to I the pin by a cross pin 18.

The locking pin 16 of eachlocking device, when in one position, isadapted to co-operate with suitable stationary abutments located. forexample,on the lbuclrstays 6 Vand 7. Short sections of angle-iron'19 and20, for example serve as convenient abutments for this purpose, Theseangle-irons may be held in place by bolts 21, and in order to' permitthe angle-irons to be exactly adjusted yserve not only to permit theabutments to be moved 'back and forth on the buck-stays, but will .alsopermit the abutments to be tilted, if desirable, in some cases, so thattheir outstanding legs will entend either in a true vertical direction,ortowards or away from the face of the door itself.

The stationary abutments should be so positioned with respect to thelocking devices that when the locking pins .are in their low-V eredpositions, their end portions will engage the abutments in a loclringfashion, whereas when the locking pins are raised to the eX- treme upperlimit of permissible movement, they will clear the abutments therebylpermitting the door to be removed. i

VIn order to make sure that a firm locking action will be secured, it isdesirable in many cases, tol so relate the slots 15 with respect totheoutstanding legs of the abutments that as the locking pins are lowered,a wedging action will be secured, thus tending to force the dooreveninore securely vinto position within its seat. This relationship canbe effected in any suitable manner, as for eX- ample by curving orslanting the slots 15, or by tilting .the abutment members, or by bothof said eXpedients. inthe construction illustrated the relationship maybev secured in either way or both ways. For example the abutments may betilted on thebuckstays, `and the slots `15 are illustrated as bef ingcurved. It will be evident, however, as the locking pins are forceddown, the door willbe wedged securely home. Y These locking pins l'serveas a very convenient means or element for engagement by the suitablelifting elements of a door machine, and in order to show one convenientmanner in which theymay be thus used for lifting the door, I haveillustrated a portion of the construction of a door machine which I willnow explain. Y `This door machine includes upper` and lower arms 22and`23 respectively which are pivoted to a suitable portion of the vdoormachine at the points 24 and 25 respectively, as clearly shown in Fig.2. Means not shown in thepresent'drawings is provided for rocking thearm 22 on its pivotal center 24 so as to raise its outerend portion 26lwhen, the load of the door is to be taken. A link 27 is providedbetween the arins 22 and 23 for` causing them to operate in more or lessunison. In the construction illustrated,` the upper end ofsaid link ispinned to the arm 22 by the pin 28. The lower end of the link 2T extendsthrough the arm 23, and springs 29 and 30 are provided for engaging theup-. per and lower faceg of said arm so that the iio tending to cause itto travel in harmony with from the locking pins. Atthe same timethethearm `VNevertheless, the two, arms may bejcaused to moveV relativelywith respect to each other VaV certain distance, vbut under springpressure.

4The outer or head .ends 26 and 8l of the two arms 22and 23arebifurcatedas clearly illustrated inFig. 5s'o that each of them has the-jaws 32-and33, These jawsare sep arateda sufficient distance V5toembracev the flanges 13 and Hof thecorresponding brackets l0 and 11, sothat saidjaws niay engage bothV end portions of the lockingfpins. Eachjaw is slotted as clearly shown Vinl Figs. 2 and j 4 so as to provide anupstandingnger 34 and an overhanging lip 35. rlhe fingers 34 serve tosecurely'retain the locking ping and enable the door machine to exert asuicient pull on the door to-withdraw it from the oven. v

Aft-er the door has been reseated, the arms 22 and 23 are rocked so asto lower their jaws for the purpose of discngaging them overhanging lips35 when used may be caused to force thelocking pins firmly downwardlywith sufficient pressure to insure that the door willbe wedged home inatight manner.

When the spring-.device or connection 29 and 30 isused, the sainewillinsure a proper engagement ofV thejawsof both the upper Yand lowerarrnsfwlith the .respective locki ng i pins,.the springs; in suclra'casefcompensating for any Asl ight--inetpualities inthe spacing of andlower ends of the door. A

Furthermore, these springequalizing connections when used, will insure asu'licient downward pressurefon both oi' the locking pins to make certaine wedging action. atboth the upper It will be seen that by the use ofbiurcated jaws on thelifting arms 22 andV 2 3 in conjunction with two ianges on each doorbracket there is an assurance that as theV Vwith elongated slotsextending in a generallyA vertical direction, a locking pin extendingthrough the slots of each bracket and having its end portions adapted toengage suitablev ixed stops when the door is seated, and aV centralsleeve on each pin between the flanges of the corresponding bracket,substantially as described.
